The clamp structurally comprises a bottom clamping plate, a clamping working device, a fixed plate block, a fixed clamp, a top clamping plate, machine tool fixing bolts, a first side edge clamping plate, a rocking handle fixing connector, a rocking handle, a second side edge clamping plate, a buffer mat plate and a threaded channel; andthe bottom clamping plate is connected with the clamping working device, the clamping working device is connected with the fixed plate block, the fixed plate block is connected with the fixed clamp, the fixed clamp is connected with the top clamping plate, the top clamping plate is provided with the two sets of machine tool fixing bolts. According to the clamp special for the steel casting, a workpiece is fixed through the bottom clamping plate, the first side edge clamping plate, the second side edge clamping plate and the top clamping plate, the overall structure is simple, design is reasonable, operation is convenient and quick, the danger coefficient is greatly reduced, the stability of the workpiece can be greatly improved, machining and processing are carried out, and the machining accuracy is guaranteed.

Description

technical field [0001] The invention is a special clamp for steel castings, which belongs to the field of steel castings. Background technique [0002] Steel castings are parts made of cast steel. They are steel castings, which have similar properties to cast iron, but are stronger than cast iron. Steel castings are prone to defects such as air holes and inaccurate angle positioning during the casting process, and the casing may break during long-term use. [0003] The existing patent discloses that the application number is: 201520400766.9, a vertical round steel casting fixture comprising a cylindrical steel ring, the middle and lower part of the steel ring is hinged with a plurality of eccentric grippers, and the plurality of eccentric grippers The head ring is distributed in the circumferential direction of the steel ring. The steel ring above the eccentric gripping head is provided with a locking plate. The locking plate is hingedly connected to the steel ring and rota...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a special fixture for steel castings to solve the problem that the existing steel casting fixtures are fixed by clamping on both sides, which easily causes the workpiece to deviate from the machining center, resulting in inaccurate machining and poor work. Problems with reduced accuracy and efficiency
